Answer:
$20.10
Explanation:
Let s = the cost of a small package and
l = the cost of a large package
1 small pakcage and 5 large package
1s+5l
Substitute s = $2.60 and l = $3.50
1($2.60) + 5(3.50)
= $20.10
$20.1
1 small package is $2.60
1 large package is $3.50
We multiply 3.5 * 5 since there are 5 large packages and we add 1 small package to get $20.1
